Abstract

The invention relates to a touch sensor and a touch display screen, wherein the touch sensor comprises a touch body, and a first protective layer, wherein the touch body comprises a first region and asecond region; the first region is provided with a touch line; the second region is provided with a touch lead in connection with the touch line; the second region can be bent below the first region,wherein when the second region is in a bent state, the second region comprises a base body portion which is in the same plane as the first region, a reverse bent portion located below the first region and a curved portion in connection with the reverse bent portion and the base body portion; the first protective layer is arranged on the outer side surface of the curved portion for protecting thetouch lead located on the outer side surface of the curved portion. According to the touch sensor and the touch display screen, the second region is bent and the first protective layer is arranged onthe curved portion of the second region, so that the touch effect is ensured while improving the screen-to-body ratio of the touch display device.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch sensor and a touch screen. Background technique [0002] The touch sensor of a touch display device generally includes a touch area and a frame area for arranging corresponding touch leads. When a touch sensor is applied to a touch display device, the width of the frame area directly affects the size of the touch display device. screen-to-body ratio. In order to obtain a touch display device with a high screen-to-body ratio, it is possible to reduce the number of touch leads or use relatively thin touch leads to reduce the width of the frame area and increase the screen-to-body ratio of the touch display device. . However, the above method may easily lead to low sensitivity of the touch sensor, which affects the touch effect. Contents of the invention [0003] Based on this, it is necessary to provide a touch sensor and a touch display screen to address the above problem...
